Tax Day Count is an iOS mobile application that tracks users’ physical-presence days across countries and regions to help determine tax-residency status. Aimed at expatriates, digital nomads, and frequent travellers, it automates day-counting rules to support compliance with international and domestic residency tests.
The app automatically logs the number of days spent in each jurisdiction using the phone’s location data and configurable calendar inputs. It supports major residency frameworks such as the 183-day rule, the UK Statutory Residence Test, the US Substantial Presence Test, and Schengen-area visa limits. Users can generate reports showing day totals by country or state for tax filings, audits, or immigration purposes.
Tax Day Count offers jurisdiction-specific presets (for example, 90/180-day Schengen calculations) and alerts when users near key thresholds such as 90- or 183-day limits. Overnight-stay tracking and manual data entry fill gaps when GPS data are incomplete. Export options provide evidence suitable for professional advisers or authorities.
Location information is processed on-device or via encrypted cloud storage, depending on settings. No data are shared with third parties, and users can request deletion of stored records. The app emphasises self-assessment and carries a disclaimer that it is not affiliated with any tax agency or government.
